BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to a keyswitch, and more particularly, toa keyswitch with adjustable tactile feedback.

2. Description of the Prior Art

A keyboard, which is the most common input device, could be found invariety of electronic apparatuses for users to input characters,symbols, numerals and so on. Furthermore, from consumer electronicproducts to industrial machine tools, they are all equipped with akeyboard for performing input operations.

In actual application, there are various kinds of keyswitches forproviding different tactile feedbacks. For example, the tactile feedbackmay be varied by high or low triggering position between an elasticpiece and a conductive electrode, long or short travel distance,required actuation force of the keyswitch, tactile or linear feedback ofthe keyswitch, clicky or non-clicky tactile feedback of the keyswitch,etc. That is to say, a conventional mechanical keyswitch only providesone single kind of tactile feedback without a tactile feedback adjustingfunction. Thus, if the user wants to experience different kinds oftactile feedbacks, the user must buy a new keyboard or replace theoriginal keyswitches on the gaming keyboard with new keyswitches forproviding another kind of tactile feedback. In such a manner, it wouldcause a high replacement cost, so as to greatly limit flexibility in useand operational convenience of the mechanical keyswitch.

DETAILED DESCRIPTION

Please refer to FIG. 1 and FIG. 2. FIG. 1 is a diagram of a keyboard 10according to an embodiment of the present invention. FIG. 2 is anenlarged diagram of a region R shown in FIG. 1. The keyboard 10 includesa plurality of keyswitches 12 and an adjusting component 14, and theadjusting component 14 is connected to the plurality of keyswitches 12simultaneously. A user can move the adjusting component 14 tosimultaneously switch the plurality of keyswitches 12 between differenthand feeling modes. The keyswitch 12 has several possible embodiments,and the user can operate the adjusting component 14 to determine how thehand feeling mode of the keyboard 10 is manually switched according toactual demand.

Please refer to FIG. 3 to FIG. 10. FIG. 3 and FIG. 4 respectively areexploded diagrams of the keyswitch 12A in different views according to afirst embodiment of the present invention. FIG. 5 and FIG. 6respectively are diagrams of the keyswitch 12A without an upper cover 18in different hand feeling modes according to the first embodiment of thepresent invention. FIG. 7 and FIG. 8 respectively are sectional views ofthe keyswitch 12A with the upper cover 18 in different pressing modesalong line A-A′ shown in FIG. 5. FIG. 9 and FIG. 10 respectively aresectional views of the keyswitch 12A with the upper cover 18 indifferent pressing modes along line B-B′ shown in FIG. 6.

The keyswitch 12A includes a substrate 16, the upper cover 18, an uppersleeve component 20, a lower sleeve component 22, a keycap 24 and arecovering component 26. The substrate 16 is disposed on a bottom of thekeyboard 10 or a printed circuit board. The upper cover 18 is disposedon the substrate 16. The upper sleeve component 20 is disposed on theupper cover 18 in an upwardly and downwardly movable manner at avertical direction. The lower sleeve component 22 is movably disposedbetween the substrate 16 and the upper cover 18, and the recoveringcomponent 26 is disposed between the substrate 16 and the lower sleevecomponent 22. The recovering component 26 is used to upwardly push thelower sleeve component 20. The upper sleeve component 20 includes akeycap connecting portion 28, a first bottom surface 30 and a secondbottom surface 32. The keycap connecting portion 28 can be assembledwith the keycap 24. The first bottom surface 30 is lower than the secondbottom surface 32, which means the first bottom surface 30 can protrudefrom the second bottom surface 32. In addition, the lower sleevecomponent 22 includes a first top surface 34 and a second top surface36, and the first top surface 34 is higher than the second top surface36, which means the first top surface 34 is stuck out of the second topsurface 36.

The substrate 16 includes a constraining pillar 38. The lower sleevecomponent 22 includes a main body 40 and a pushing portion 42. The mainbody 40 is movably disposed on the constraining pillar 38, and thepushing portion 42 stretches from a surface of the main body 40 to bepartly exposed out of the substrate 16. Therefore, when the usermanually presses the pushing portion 42 of each of the plurality ofkeyswitches 12, or utilizes the adjusting component 14 to simultaneouslypush the pushing portions 42 of the plurality of keyswitches 12, themain body 40 is guided by the pushing portion 42 and can be levellyrotated relative to the constraining pillar 38 at a right direction anda left direction. Besides, the upper sleeve component 20 furtherincludes a sliding portion 44 movably disposed inside a sliding slot 46formed on the upper cover 18. While the keycap 24 is manually pressed,the keycap 24 can be moved relative to the upper cover 18 via thesliding portion 44 upwardly and downwardly at the vertical direction;the sliding slot 46 further can be used to prevent the upper sleevecomponent 20 from being levelly rotated relative to the upper cover 18.

The substrate 16 further includes an electrode module 48, and theelectrode module 48 includes a first electrode sheet 50 and a secondelectrode sheet 52. The first electrode sheet 50 is inserted into abottom inside the substrate 16, and the second electrode sheet 52 ispasted on an inner wall of the substrate 16 and located between thefirst electrode sheet 50 and the lower sleeve component 22. The secondelectrode sheet 52 includes an elastic portion 54 movably contactingagainst the lower sleeve component 22. The lower sleeve component 22 canbe interfered with the electrode module 48 while the lower sleevecomponent 22 is moved relative to the constraining pillar 38 of thesubstrate 16 vertically. That is to say, the elastic portion 54 of thesecond electrode sheet 52 can contact against and be separated from thefirst electrode sheet 50 in accordance with upward and downward motionof the lower sleeve component 22 for triggering the keyswitch 12A.

The lower sleeve component 22 further includes a first vertical lateralsurface 56 and a second vertical lateral surface 58, and a shape of thefirst vertical lateral surface 56 is different form a shape of thesecond vertical lateral surface 58. The first vertical lateral surface56 is connected to the first sectional inclined surface 60, the secondvertical lateral surface 58 is connected to the second sectionalinclined surface 62, and a distance between the first sectional inclinedsurface 60 and bottom of the main body 40 is greater than a distancebetween the second sectional inclined surface 62 and the bottom of themain body 40, which means the first sectional inclined surface 60 can behigher than the second sectional inclined surface 62. While the elasticportion 54 of the second electrode sheet 52 contacts against the firstvertical lateral surface 56 or the second vertical lateral surface 58,the second electrode sheet 52 is not electrified by the first electrodesheet 50; while the elastic portion 54 contacts against the firstsectional inclined surface 60 or the second sectional inclined surface62, the second electrode sheet 52 and the first electrode sheet 50 areelectrified.

The lower sleeve component 22 can be levelly rotated relative to theconstraining pillar 38 of the substrate 16, so as to switch between afirst angle position shown in FIG. 6 and a second angle position shownin FIG. 5. When the lower sleeve component 22 is set in the first angleposition, the lower sleeve component 22 contacts against the uppersleeve component 20, the first bottom surface 30 abuts the first topsurface 34, the second bottom surface 32 does not abut the second topsurface 36, a gap between the substrate 16 and bottom of the lowersleeve component 22 is smaller, so that the recovering component 26 hasa first length H1; in the meantime, the elastic portion 54 contactsagainst the first vertical lateral surface 56, as shown in FIG. 9. Whenthe keyswitch 12A is pressed, the recovering component 26 is compressedaccordingly and compression is stopped until the bottom of the lowersleeve component 22 contacts the substrate 16. The elastic portion 54 ismoved from the first vertical lateral surface 56 to the first sectionalinclined surface 60, and the electrode module 48 is electrified togenerate a control signal of the keyswitch 12A, as shown in FIG. 10. Inthis hand feeling mode, the keyswitch 12A provides shorter pressingtravel distance, the user exerts large force upon the keyswitch 12A fordownward motion because the recovering component 26 has greater requiredactuation force quantity, which means heavy hand feeling is acquired.

When the lower sleeve component 22 is set in the second angle position,the lower sleeve component 22 contacts against the upper sleevecomponent 20, the first bottom surface 30 abuts the second top surface36, the second bottom surface 32 abuts the first top surface 34, the gapbetween the substrate 16 and bottom of the lower sleeve component 22 islarger, so that the recovering component 26 has a second length H2;meanwhile, the elastic portion 54 contacts against the second verticallateral surface 58, as shown in FIG. 7, and the second length H2 isgreater than the first length H1. When the keyswitch 12A is pressed, therecovering component 26 is compressed accordingly and compression isstopped until the bottom of the lower sleeve component 22 contacts thesubstrate 16, the elastic portion 54 is moved from the second verticallateral surface 58 to the second sectional inclined surface 62, and theelectrode module 48 is electrified to generate the control signal of thekeyswitch 12A, as shown in FIG. 8. In this hand feeling mode, thekeyswitch 12A can provide longer pressing travel distance, therecovering component 26 has smaller required actuation force quantity,and the user exerts large force upon the keyswitch 12A for downwardmotion.

Thus, the first embodiment of the present invention disposes the firstbottom surface 30 and the second bottom surface 32 on the bottom of theupper sleeve component 20, disposes the first top surface 34 and thesecond top surface 36 corresponding to the bottom surfaces 30 and 32 ontop of the lower sleeve component 22, the upper sleeve component 20 isconstrained by the upper cover 18 and cannot be rotated levelly.Rotation of the lower sleeve component 22 can change the gap between theupper sleeve component 20 and the lower sleeve component 22, an initialheight of the lower sleeve component 22 relative to the substrate 16 isadjustable, so that the recovering component 26 has dissimilar requiredactuation force quantity for providing different hand feeling modes. Anouter surface of the lower sleeve component 22 has the first verticallateral surface 56 and the first sectional inclined surface 60 matchedwith the first angle position, and further has the second verticallateral surface 58 and the second sectional inclined surface 62 matchedwith the second angle position, hence the keyswitch 12A can provideidentical trigger travel distance at any angle position.

Please refer to FIG. 11 to FIG. 18. FIG. 11 and FIG. 12 respectively areexploded diagrams of the keyswitch 12B in different views according to asecond embodiment of the present invention. FIG. 13 and FIG. 14respectively are diagrams of the keyswitch 12B without the upper cover18 in different hand feeling modes according to the second embodiment ofthe present invention. FIG. 15 is a sectional view of the keyswitch 12Bwith the upper cover 18 along line C-C′ shown in FIG. 13. FIG. 16 is asectional view of the keyswitch 12B with the upper cover 18 along lineD-D′ shown in FIG. 13.

Therefore, when the usermanually presses the pushing portion 42 of each of the plurality ofkeyswitches 12, or utilizes the adjusting component 14 to simultaneouslypush the pushing portions 42 of the plurality of keyswitches 12, themain body 40 is guided by the pushing portion 42 and can be levellyrotated relative to the constraining pillar 38. Moreover, the uppersleeve component 20 further includes the sliding portion 44 movablydisposed inside the sliding slot 46 formed on the upper cover 18. Whilethe keycap 24 is pressed, the keycap 24 can be moved relative to theupper cover 18 via the sliding portion 44 upwardly and downwardly at thevertical direction; the sliding slot 46 further can be utilized toprevent the upper sleeve component 20 from being levelly rotatedrelative to the upper cover 18.

The secondelectrode sheet 52 includes the elastic portion 54 movably contactingagainst the lower sleeve component 22′. The lower sleeve component 22′can be interfered with the electrode module 48 while the lower sleevecomponent 22′ is moved relative to the constraining pillar 38 of thesubstrate 16 vertically. That is, the elastic portion 54 of the secondelectrode sheet 52 can contact against and be separated from the firstelectrode sheet 50 in accordance with upward and downward motion of thelower sleeve component 22′ for an aim of triggering the keyswitch 12B.

The lower sleeve component 22′ further includes the first verticallateral surface 56 and the second vertical lateral surface 58, and theshape of the first vertical lateral surface 56 is different form theshape of the second vertical lateral surface 58.

While the elastic portion 54 of the second electrode sheet52 contacts against the first vertical lateral surface 56 or the secondvertical lateral surface 58, the second electrode sheet 52 is notelectrified by the first electrode sheet 50; while the elastic portion54 contacts against the first sectional inclined surface 60 or thesecond sectional inclined surface 62, the second electrode sheet 52 andthe first electrode sheet 50 are electrified.

The lower sleeve component 22′ can be levelly rotated relative to theconstraining pillar 38 of the substrate 16, so as to switch between thefirst angle position shown in FIG. 13 and the second angle positionshown in FIG. 14. When the lower sleeve component 22′ is set in thefirst angle position, the second bottom surface 70 of the lower sleevecomponent 22′ does not align with the first top surface 64 of thesubstrate 16′; if the keyswitch 12B is pressed, the lower sleevecomponent 22′ can be moved downward until the first bottom surface 68abuts the first top surface 64, the elastic portion 54 is moved from thesecond vertical lateral surface 58 to the second sectional inclinedsurface 62, and the electrode module 48 is electrified to trigger thekeyswitch, as shown in FIG. 15 and FIG. 16, and upward and downwardmotion of the lower sleeve component 22′ has a first travel distance S1.When the lower sleeve component 22′ is set in the second angle position,the second bottom surface 70 of the lower sleeve component 22′ alignswith the first top surface 64 of the substrate 16′, and the first bottomsurface 68 aligns with the second top surface 66; when the keyswitch 12Bis pressed, the lower sleeve component 22′ is moved downwardly anddownward motion is stopped until the first bottom surface 68 abuts thesecond top surface 66 and the second bottom surface 70 abuts the firsttop surface 64, the elastic portion 54 can be moved from the firstvertical lateral surface 56 to the first sectional inclined surface 60,the electrode module 48 is electrified to trigger the keyswitch, asshown in FIG. 17 and FIG. 18, upward and downward motion of the lowersleeve component 22′ has a second travel distance S2, and the secondtravel distance S2 is greater than the first travel distance S1.

The first bottom surface 30 is lowerthan the second bottom surface 32, which means the first bottom surface30 can protrude from the second bottom surface 32; however, the firstbottom surface 30 and the second bottom surface 32 are optional design,the upper sleeve component 20 may have no bottom surfaces with stagevariation, and can directly utilize the same flat surface to contactagainst the top of the lower sleeve component 22″.

The substrate 16 includes the constraining pillar 38. The lower sleevecomponent 22″ includes the main body 40 and the pushing portion 42. Themain body 40 is movably disposed on the constraining pillar 38, and thepushing portion 42 stretches from the surface of the main body 40 to bepartly exposed out of the substrate 16. Therefore, when the usermanually presses the pushing portion 42 of each of the plurality ofkeyswitches 12, or utilizes the adjusting component 14 to simultaneouslypush the pushing portions 42 of the plurality of keyswitches 12, themain body 40 is guided by the pushing portion 42 and can be levellyrotated relative to the constraining pillar 38. Besides, the uppersleeve component 20 further includes the sliding portion 44 movablydisposed inside the sliding slot 46 formed on the upper cover 18. Whilethe keycap 24 is pressed, the keycap 24 can be moved relative to theupper cover 18 via the sliding portion 44 in an upwardly and downwardlymovable manner at the vertical direction; the sliding slot 46 furthercan be used to prevent the upper sleeve component 20 from being levellyrotated relative to the upper cover 18.

The lower sleeve component 22″can be interfered with the electrode module 48 while the lower sleevecomponent 22″ is moved relative to the constraining pillar 38 of thesubstrate 16 vertically. Thus, the elastic portion 54 of the secondelectrode sheet 52 can contact against and be separated from the firstelectrode sheet 50 in accordance with upward and downward motion of thelower sleeve component 22″ for triggering the keyswitch 12C.

The lower sleeve component 22″ further includes the first verticallateral surface 56 and the second vertical lateral surface 58, and theshape of the first vertical lateral surface 56 is different form theshape of the second vertical lateral surface 58.

While the elastic portion 54 of the second electrode sheet52 contacts against the first vertical lateral surface 56 or the secondvertical lateral surface 58, the second electrode sheet 52 is notelectrified by the first electrode sheet 50; while the elastic portion54 contacts against the first sectional inclined surface 60 or thesecond sectional inclined surface 62, the second electrode sheet 52 andthe first electrode sheet 50 are electrified.

The lower sleeve component 22″ can be levelly rotated relative to theconstraining pillar 38 of the substrate 16, so as to switch between thefirst angle position shown in FIG. 22 and the second angle positionshown in FIG. 21. When the lower sleeve component 22″ is set in thefirst angle position, the keyswitch 12C is manually pressed, the elasticportion 54 is moved from the first vertical lateral surface 56 to thefirst sectional inclined surface 60, and the electrode module 48 iselectrified to trigger the keyswitch 12C, as shown in FIG. 24. When thelower sleeve component 22″ is set in the second angle position, thekeyswitch 12C is manually pressed, and the elastic portion 54 is movedfrom the second vertical lateral surface 58 to the second sectionalinclined surface 62, so that the electrode module 48 is electrified totrigger the keyswitch 12C, as shown in FIG. 23. In the third embodiment,the keyswitch 12C has the identical pressing depth travel distance whilebeing switched to the first angle position and the second angleposition, rotation of the lower sleeve component 22″ does not affect therequired actuation force quantity of the recovering component 26.However, the outer surface of the lower sleeve component 22″ has theinclined surfaces with stage difference, the elastic portion 54 in thefirst angle position is electrified by the electrode module 48 while thelower sleeve component 22″ is moved deeper (such as a lower position),the user may press the keyswitch 12C to a lowest position for outputtingthe control signal; the elastic portion 54 in the second angle positioncan be electrified by the electrode module 48 while the lower sleevecomponent 22″ is moved in the shallow (such as a higher position), theuser can press the keyswitch 12C to a middle position for outputting thecontrol signal, and the middle position is higher than the lowestposition.

Themain body 40 is movably disposed on the constraining pillar 38, and thepushing portion 42 stretches from the surface of the main body 40 to bepartly exposed out of the substrate 16. Therefore, when the usermanually presses the pushing portion 42 of each of the plurality ofkeyswitches 12, or utilizes the adjusting component 14 to simultaneouslypush the pushing portions 42 of the plurality of keyswitches 12, themain body 40 is guided by the pushing portion 42 and can be levellyrotated relative to the constraining pillar 38.

While the lower sleeve component22″ is set in the first angle position, the third vertical lateralsurface 76 faces the resilient arm unit 74, the fourth vertical lateralsurface 78 is distant from the resilient arm unit 74, the keyswitch 12Eis pressed to downwardly move the lower sleeve component 22″ along theconstraining pillar 38, the resilient arm unit 74 is affected by theresistance protrusion 80 to generate the tactile feedback. When theresilient arm unit 74 is moved across the resistance protrusion 80 forrecovery, the resilient arm unit 74 can hit one of the upper cover 18and the substrate 16 to generate noise, as shown in FIG. 33.

With regard tothe adjusting method of changing the operational hand feeling of thekeyboard 10, step S420 is executed first that the controller 82 isactuated to detect an operational parameter from the computer or thekeyboard 10. Then, step S422 is executed to determine whether theoperational parameter conforms to the predefined condition. As the firstpredefined condition is conformed, step S424 is executed that thecontroller 82 sets the plurality of keyswitches 12 in the first handfeeling mode; as the second predefined condition is conformed, step S426is executed that the controller 82 sets the plurality of keyswitches 12in the second hand feeling mode.

The operational parameter can be various types, and its variation is notlimited to the following embodiments, which depends on design demand.For example, the operational parameter can be a category of theapplication program executed by an active window of the computer, suchas document program and game program. The first predefined condition maydefine the document program (such like Microsoft Word) belonging to thefirst category, and the second predefined condition may define the gameprogram (such like Blizzard Overwatch) belonging to the second category.Therefore, while the application program executed by the computerbelongs to the first category, the plurality of keyswitches 12 can beswitched to the first hand feeling mode; while the application programexecuted by the computer belongs to the second category, the pluralityof keyswitches 12 can be switched to the second hand feeling mode. Thevarious hand feeling modes may be selected from a group consisted ofworking travel distance, pressing feedback, triggering depth, clickysound, clicky resistance, and a combination thereof. The user can adjustforesaid factors in the hand feeling mode in accordance with theapplication program.

The operational parameter further can be set as press frequency of theplurality of keyswitches 12. The first predefined condition may definethat the press frequency of the plurality of keyswitches 12 is greaterthan a predefined value, therefore when the press frequency of theplurality of keyswitches 12 is greater than the predefined value, suchas the keyswitch 12 being pressed rapidly in high frequency, theplurality of keyswitches 12 is switched to the first hand feeling mode.The second predefined condition may define that the press frequency ofthe plurality of keyswitches 12 is smaller than the predefined value,when the press frequency of the plurality of keyswitches 12 is smallerthan the predefined value, the keyswitch 12 is pressed slowly andoccasionally, and the plurality of keyswitches 12 is switched to thesecond hand feeling mode.

The operational parameter further can be set as a number of pressing theplurality of keyswitches 12 within a predefined period. For instance,the first predefined condition may define that the number of pressingwithin the predefined period is greater than the predefined value, whenthe number of pressing within the predefined period is greater than thepredefined value, the plurality of keyswitches 12 is switched to thefirst hand feeling mode; the second predefined condition may define thatthe number of press within the predefined period is smaller than thepredefined value, when the number of pressing within the predefinedperiod is smaller than the predefined value, the plurality ofkeyswitches 12 is switched to the second hand feeling mode.

Switching of the keyswitch 12 can be manually operated by the user, asshown in FIG. 1, holes on the adjusting component 14 are respectivelyengaged with the pushing portions 42 of the plurality of keyswitches 12,the user can push the adjusting component 14 to simultaneously switchthe plurality of keyswitches 12 into the first hand feeling mode or thesecond hand feeling mode. Additionally, the keyboard 10 may have adriving device 84, such as an electric motor. When the controller 82detects that the operational parameter conforms to the first predefinedcondition or the second predefined condition, the user can start off thedriving device 84 to move the adjusting component 14, so as tosimultaneously switch the plurality of keyswitches 12 into one of thefirst hand feeling mode and the second hand feeling mode.
